Red Sox manager John Farrell can see the progression Owens has made since last Spring Training.
"Poise. Confidence," Farrell said. "His breaking ball to me this spring is a little tighter and a little more sharp than we saw a year ago. He's starting to, I think, through physical maturity and gaining some weight and overall strength, develop a little better fastball velocity."
Along with Matt Barnes, who has also been impressive in early Grapefruit League outings, Owens gives the Red Sox some good depth at Triple-A if one of the projected five starting pitchers suffers an injury.
"He flashed some good fastballs today," said Farrell. "His changeup is always going to be the signature pitch for him. The three pitches that he has have such definition that he can attack a guy multiple ways."
